Well as a supporter of virtuemart, the team you say and a few people they say, they are, great people doing great job.
I think you folks having problems with virtuemart default shipped modules, should do something about your needs. I'm sure there is plenty of free and payed extensions out there, and as one of the team members said, if you can't find it, fork it!
Make an extension for your needs.
In my recent projects, Since VM 2.9 beta, I choose to migrate to the latest version, and the result was that in my country, Iran, I was the first one to release a Payment Plugin for VM3 and I also managed to develop some slider, scroller, carousel, and so many other modules.
So the answer to your question is,
RANDOM FEATURED PRoducts is a must, in my opinion! It's so usefull when you have aroun 40 featured products and you want a random slideshow of 10 on each visit!
So I think instead of asking nonsense question On why You did this, why not that, Just Engage your self to the project!
I mean if you really don wanna contribute to the project and donate your extensions too, just go deep in to their codes. See how clearly coded they have coded the applications and how it's easy for you to get what you need out of the default shipped files. Even if you do not have enough php knowledge you still can do what you want around with virtuemart. That's been my experience since 6 years ago with VM!
